For U.S.A. s13aa The following information has been compiled according to Code of Federal Regulations “Title 49, Part 575”. 13-2. Tire Information s13ab & Tire Labeling s13ab01 Many markings (e.g. Tire size, Tire Identification Number or TIN) are placed on the sidewall of a tire by tire manufacturers. These marking can provide you with useful information on the tire. ! Tire size s13ab0101 Your vehicle comes equipped with P-Metric tire size. It is important to understand the sizing system in selecting the proper tire for your vehicles. Here is a brief review of the tire sizing system with a breakdown of its individual elements. ! P Metric s13ab010101 With the P-Metric system, Section Width is measured in millimeters. To convert millimeters into inches, divide by 25.4. The Aspect Ratio (Section Height divided by Section Width) helps provide more dimensional information about the tire size. Example: (1) P = Certain tire type used on light duty vehicles such as passenger cars (2) Section Width in millimeters (3) Aspect Ratio (= section height 7 section width). (4) R = Radial Construction (5) Rim diameter in inches ! Load and Speed Rating Descriptions s13ab010102 The load and speed rating descriptions will appear following the size designation. They provide two important facts about the tire. First, the number designation is its load index. Second, the letter designation indicates the tire’s speed rating. 498 For U.S.A. Example: (6) Load Index: A numerical code which specifies the maximum load a tire can carry at the speed indicated by its speed symbol, at maximum inflation pressure. For example, “91” means 1,356 lbs (615 kg), “90” means 1,323 lbs (600 kg), “89” means 1,279 lbs (580 kg) WARNING Load indices apply only to the tire, not to the vehicle. Putting a load rated tire on any vehicle does not mean the vehicle can be loaded up to the tire’s rated load. (7) Speed Rating: An alphabetical system describing a tire’s capability to travel at established and predetermined speeds. For example, “V” means 149 mph (240 km/h) WARNING . Speed ratings apply only to the tire, not to the vehicle. Putting a speed rated tire on any vehicle does not mean the vehicle can be operated at the tire’s rated speed. . The speed rating is void if the tires are worn out, damaged, repaired, retreaded, or otherwise altered from their original condition. If tires are repaired, retreaded, or otherwise altered, they may not be suitable for original equipment tire designed loads and speeds. ! Tire Identification Number (TIN) s13ab0102 Tire Identification Number (TIN) is marked on the intended outboard sidewall. Here is a brief review of the TIN with a breakdown of its individual elements. Type A (1) DOT symbol* (2) Manufacturer’s Identification Mark (3) Tire Size Code (4) Tire Type Code (5) Date of Manufacture The first two figures identify the week, starting with “01” to represent the first full week of the calendar year; the second two figures represent the year. For example, 0101 means the 1st week of 2001. *: The DOT symbol certifies that the tire conforms to applicable Federal Motor Vehicle Safety Standards. – CONTINUED – Tire Information 499 13 Consumer Information and Reporting Safety Defects Type B (1) DOT symbol* (2) Plant Code (3) Manufacturer’s Code (4) Date of Manufacture The first two figures identify the week, starting with “01” to represent the first full week of the calendar year; the second two figures represent the year. For example, 0101 means the 1st week of 2001. *: The DOT symbol certifies that the tire conforms to applicable Federal Motor Vehicle Safety Standards. ! Other markings s13ab0103 The following makings are also placed on the sidewall. ! Maximum permissible inflation pressure s13ab010301 The maximum cold inflation pressure to which this tire may be inflated. For example, “350 kPa (51 PSI) MAX. PRESS” ! Maximum load rating s13ab010302 The load rating at the maximum permissible weight load for this tire. For example, “MAX. LOAD 615 kg (1,356 LBS) @ 350 kPa (51 PSI) MAX. PRESS.” WARNING Maximum load rating applies only to the tire, not to the vehicle. Putting a load rated tire on any vehicle does not mean the vehicle can be loaded up to the tire’s rated load. ! Construction type s13ab010303 Applicable construction of this tire. For example, “TUBELESS STEEL BELTED RADIAL” ! Construction s13ab010304 The generic name of each cord material used in the plies (both sidewall and tread area) of this tire. For example, “PLIES: TREAD 2 STEEL + 2 POLYESTER + 1 NYLON SIDEWALL 2 POLYESTER” ! Uniform Tire Quality Grading (UTQG) s13ab010305 For details, refer to “Uniform Tire Quality Grading Standards” P511. & Recommended Tire Inflation Pressure s13ab02 ! Recommended cold tire inflation pressure s13ab0201 For the recommended cold tire inflation pressure for your vehicle’s tires, refer to “Tires” P489. 500 Tire Information ! Vehicle placard s13ab0202 The vehicle placard is affixed to the driver’s side B-pillar. Example: The vehicle placard shows original tire size, recommended cold tire inflation pressure on each tire at maximum loaded vehicle weight, seating capacity and loading information. ! Adverse safety consequences of under-inflation s13ab0203 Driving at high speeds with excessively low tire pressures can cause the tires to flex severely and to rapidly become hot. A sharp increase in temperature could cause tread separation, and failure of the tire(s). Possible resulting loss of vehicle control could lead to an accident. ! Measuring and adjusting air pressure to achieve proper inflation s13ab0204 Check and, if necessary, adjust the pressure of each tire (including the spare) at least once a month and before any long journey. Check the tire pressures when the tires are cold. Use a pressure gauge to adjust the tire pressures to the specific values. Driving even a short distance warms up the tires and increases the tire pressures. Also, the tire pressures are affected by the outside temperature. It is best to check tire pressure outdoors before driving the vehicle. When a tire becomes warm, the air inside it expands, causing the tire pressure to increase. Be careful not to mistakenly release air from a warm tire to reduce its pressure. & Glossary of Tire Terminology s13ab03 .

Check on a daily basis that the tires are free from serious damage, nails, and stones. At the same time, check the tires for abnormal wear. . Inspect the tire tread regularly and replace the tires before their tread wear indicators become visible. When a tire’s tread wear indicator becomes visible, the tire is worn beyond the acceptable limit and must be replaced immediately. With a tire in this condition, driving at even low speeds in wet weather can cause the vehicle to hydroplane. Possible resulting loss of vehicle control can lead to an accident. . To maximize the life of each tire and ensure that the tires wear uniformly, it is best to rotate the tires every 6,000 miles (10,000 km). For details about tire rotation, refer to “Tire Rotation” P460. Replace any damaged or unevenly worn tire at the time of rotation. After tire rotation, adjust the tire pressures and make sure the wheel nuts are correctly tightened. For information about the tightening torque and tightening sequence for the wheel nuts, refer to “Tire Replacement” P461. & Vehicle Load Limit – How to Determine s13ab05 The load capacity of your vehicle is determined by weight, not by available cargo space. The load limit of your vehicle is shown on the vehicle placard attached to the driver’s side B-pillar. Locate the statement “The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs” on your vehicle’s placard. The vehicle placard also shows seating capacity of your vehicle. The total load capacity includes the total weight of driver and all passengers and their belongings, any cargo, any optional equipment such as a trailer hitch, roof rack or bike carrier, etc., and the tongue load of a trailer. Therefore cargo capacity can be calculated by the following method. Cargo capacity = Load limit − (total weight of occupants + total weight of optional equipment + tongue load of a trailer (if applicable)) ! Calculating total and load capacities varying seating configurations s13ab0501 Calculate the available load capacity as shown in the following examples: 506 Tire Information Example 1A Vehicle capacity weight of the vehicle is 800 lbs (363 kg), which is indicated on the vehicle placard with the statement “The combined weight of occupants and cargo should never exceed 363 kg or 800 lbs”. For example, if the vehicle has one occupant weighing 154 lbs (70 kg) plus cargo weighing 551 lbs (250 kg). 1. Calculate the total weight. 2. Calculate the available load capacity by subtracting the total weight from the vehicle capacity weight of 800 lbs (363 kg). 3. The result of step 2 shows that a further 95 lbs (43 kg) of cargo can be carried. Example 1B For example, if a person weighing 176 lbs (80 kg) now enters the same vehicle (bringing the number of occupants to two), the calculations are as follows: 1. Calculate the total weight. – CONTINUED – Tire Information 507 13 Consumer Information and Reporting Safety Defects 2. Calculate the available load capacity. 3. The total weight now exceeds the capacity weight by 81 lbs (37 kg), so the cargo weight must be reduced by 81 lbs (37 kg) or more. Example 2A CAUTION Your vehicle is neither designed nor intended to be used for trailer towing. Therefore, never tow a trailer with your vehicle. Vehicle capacity weight of the vehicle is 800 lbs (363 kg), which is indicated on the vehicle placard with the statement “The combined weight of occupants and cargo should never exceed 363 kg or 800 lbs”. For example, the vehicle has one occupant weighing 165 lbs (75 kg) plus cargo weighing 265 lbs (120 kg). In addition, the vehicle is fitted with a trailer hitch weighing 22 lbs (10 kg), to which is attached a trailer weighing 1,764 lbs (800 kg). 10% of the trailer weight is applied to the trailer tongue (i.e. Tongue load = 176 lbs (80 kg)). 1. Calculate the total weight. 2. Calculate the available load capacity. 3. The result of step 2 shows that a further 172 lbs (78 kg) of cargo can be carried. 508 Tire Information Example 2B CAUTION Your vehicle is neither designed nor intended to be used for trailer towing. Therefore, never tow a trailer with your vehicle. For example, if a person weighing 143 lbs (65 kg) and a child weighing 40 lbs (18 kg) now enter the same vehicle (bringing the number of occupants to three), and a child restraint system weighing 11 lbs (5 kg) is installed in the vehicle for the child to use, the calculations are as follows: 1. Calculate the total weight. 2. Calculate the available load capacity. 3. The total weight now exceeds the capacity weight by 22 lbs (10 kg), so the cargo weight must be reduced by 22 lbs (10 kg) or more. & Determining Compatibility of Tire and Vehicle Load Capacities s13ab06 The sum of four tires’ maximum load ratings must exceed the maximum loaded vehicle weight (“GVWR”). In addition, sum of the maximum load ratings of two front tires and of two rear tires must exceed each axle’s maximum loaded capacity (“GAWR”). Original equipment tires are designed to fulfill those conditions. The maximum loaded vehicle weight is referred to Gross Vehicle Weight Rating (GVWR). And each axle’s maximum loaded capacity is referred to Gross Axle Weight Rating (GAWR). The GVWR and each axle’s GAWR are shown on the vehicle certification label affixed to the driver’s door. The GVWR and front and rear GAWRs are determined by not only – CONTINUED – Tire Information 509 13 Consumer Information and Reporting Safety Defects the maximum load rating of tires but also loaded capacities of the vehicle’s suspension, axles and other parts of the body. Therefore, this means that the vehicle cannot necessarily be loaded up to the tire’s maximum load rating on the tire sidewall. & Adverse Safety Consequences of Overloading on Handling and Stopping and on Tires s13ab07 Overloading could affect vehicle handling, stopping distance, vehicle and tire as shown in the following. This could lead to an accident and possibly result in severe personal injury. . Vehicle stability will deteriorate. . Heavy and/or high-mounted loads could increase the risk of rollover. . Stopping distance will increase. . Brakes could overheat and fail. . Suspension, bearings, axles and other parts of the body could break or experience accelerated wear that will shorten vehicle life. . Tires could fail. . Tread separation could occur. . Tire could separate from its rim. & Steps for Determining Correct Load Limit s13ab08 1. Locate the statement “The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs.” on your vehicle’s placard. 2. Determine the combined weight of the driver and passengers that will be riding in your vehicle. 3. Subtract the combined weight of the driver and passengers from XXX kg or XXX lbs. 4. The resulting figure equals the available amount of cargo and luggage load capacity. For example, if the “XXX” amount equals 1,400 lbs (635 kg) and there will be five 150 lbs (68 kg) passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs (1,400 − 750 (5 6 150) = 650 lbs). 5. Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in Step 4. 6. If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult this manual to determine how this reduces the available cargo and luggage load capacity of your vehicle. 510 Tire Information 13-3. Uniform Tire Quality Grading Standards s13ac This information indicates the relative performance of passenger car tires in the area of treadwear, traction, and temperature resistance. This is to aid the consumer in making an informed choice in the purchase of tires. Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width. For example: TREADWEAR 200 TRACTION AA TEMPERATURE A The quality grades apply to new pneumatic tires for use on passenger cars. However, they do not apply to deep tread, winter type snow tires, space-saver or temporary use spare tires, tires with nominal rim diameters of 12 inches or less, or to some limited production tires. All passenger car tires must conform to Federal Safety Requirements in addition to these grades. & TREADWEAR s13ac02 The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and one-half (1- 1/2) times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate. & TRACTION AA, A, B, C s13ac03 The traction grades, from highest to lowest, are AA, A, B and C. Those grades represent the tire’s ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. WARNING The traction grade assigned to this tire is based on straightahead braking traction tests, and does not include acceleration, cornering, hydroplaning, or peak traction characteristics. & TEMPERATURE A, B, C s13ac04 The temperature grades are A (the highest), B, and C, representing the tire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature – CONTINUED – Uniform Tire Quality Grading Standards 511 13 Consumer Information and Reporting Safety Defects can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law. WARNING The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or exc
